SPECIFICATION forming part of Letters Patent No. 788,510, dated May 2,1905.

Application filed April 21, 1903. Serial No. 153,591.

To all whom, it r11/ay concern:

Be it known that I, ASAHEL F. BENNETT, a

citizen of the United States, residing at Oak Park, in the State ofIllinois, have invented certain new and useful Improvements in Valves,of which the following is a specification.

This invention has reference particularly to combination valves such asare commonly used in connection with bath-.tubs or other toiletroomfixtures, for controlling the iiow of the hot and cold water andregulating the temperature of the mixture thereof.

The first of the objects of this invention is the provision of a deviceof the type specilied, in conjunction with which there is provided meanswhereby the mixture of hot and cold water may be caused to flow ineither one of two directions at will, so that the temperature thereofmay be determined by feeling the water as it iiows in one direction, orout of one outlet nozzle, adjusting the hot and cold water valves so asto get just the temperature desired, and then by the shifting of thesupplemental valve the mixture of hot and cold watermay be caused toiiow through another passage or outlet Which would ordinarily beconnected to some shower-bath device, such as the common form of hosewith sprinkler nozzle attached.

Another object of this invention is the provision of a combination valvedevice in which there is combined with the hot and cold water valves asupplemental valve device arranged to control the mixture of the hot andcold water and to determine the flow thereof relative to a plurality ofoutlet openings or passages.

The above, as well as such other objects as will hereinafter appear, Iattain by means of a construction which I have illustrated in preferredform in the accompanying' drawing, in which# i Figure 1 is an endelevation of a valvular device embodying my improvements.

Figure 2 is a section on the line 2 in Figure I; and Figure 3 representsa modification showing a somewhat dierent form of supplemental valvemechanism.

Referring' particularly to Figure 1, it will be seen that I have thereinindicated the exterior of a hot water valve 4, and' a cold water valve5, which as they may be of any ordinary construction, are not indicatedin detail, but only as it were diagrammatically, the connections fromsaid hot and cold water valves joining within the part marked 6, whichcontains a` mixing chamber fr. The mixing chamber fr has two outlets,opening respectively past the valve seats 14 and 15, (see Fig. 2), bothof said valve seats being subject to control alternately by means of thevalve 13, which is actuated by the handle 10, through the crank 1l, andconnection 12, which parts `combined constitute what for convenience ofreference I shall term generally the supplemental valve device. Thewater that Hows past the seat 14, passes upward through the casing 7,and out through the nozzle 8, the said nozzle being' preferablyconstructed for attachment to the usual form of hose and sprinkler headcommonly used for showerbath purposes; and the water that passes thevalve seat 15 has its outlet through the downwardly projecting nozzle 9.

It Will be observed that with the parts in the position shown, the seatleading to the l `nozzle 8 is closed, while that leading to the nozzle 9is open. YIf now water be admitted from the hot water valve 4, and thecold water valve 5, the same being adjusted to just the right relativepositions as will cause the mixture of the two passing. from the mixingchamber m out of the nozzle 9, to be at the desired temperature, areversal of the position of the handle IO will shut ofi' the iiow to thenozzle 9, and cause the water to How upwardly through the nozzle 8, tothe showerbath arrangement attached thereto. It will further be observedthat the quantity of the water passing upward through the nozzle 8 canbe regulated to any extent desired by propell setting of the handle l0,without altering the temperature of the mixture after the same has beenonce properly fixed; for the water that does not How upward -from thechamber rv with the valve 13 in an intermediate position, will escapedownward through the nozzle 9.

In Figure 3 Ihave shown a modification in which the outlets leadingupward and downward from the mixing chamber' af, while both controlledby the single handle 10, are each provided with a separate closingvalve, 16 and 17, both of which are capable of closing either one of theoutlets from the valve chamber, so that both outlets from the mainchamber may be closed at once whether the two valves are forced upwardor forced downward. It will be noted that the valve plugs have on theinner side a long slanting face and on the outer surface a more abruptlyslanting face. Thus as shown in this ligure, the two valves may bepushed farther down, forcing the upper valve farther into its innerseat, until the lower 'valve is seated on its outer surface whichwillentirelyY close off the flow.

Vhile the drawings show what is known as the Fuller bib cock form ofvalve construction, my improvement is not limited to the employment ofany particular form of valve, as ground plug cocks, or any other knownconstruction, may be used when preferred. And though I have referred tothe employment of my improvement in conjunction with the common hosewith sprinkler nozzle attached, it is obvious that it is capable of usewith any'other form of shower bath devices in general use, such as thoseattached to the wall and suitably connected to the bath cock.

Having thus described my invention and illustrated its use in preferredform in the accompanying drawings, what I claim, and desire to secure byLetters Patent, is the following:

1. In a valve the combination of a casing having two valve controlledinlets, and two outlets, a double valve located between said two outletsin the casing, having a face seating upon each of the outlets, inalternation one face being an elongated cone, a crank shaft mounted inthe casing and a link supporting the double valve and operated by saidcrank-shaft, whereby the valve is moved be-' tween the two outlets toclose either one of them, and differentially governs the outiow from thecasing, and the valve stem may have further movement after the long coneface is seated, substantially as described.

2. The combination with a casing having two valve-controlled inlets andtwo valve-controlled outlets, of a valve device in said casing and meansfor entirely closing either one of said outlets or both of said outletssimultaneously, substantially as described.

3. The combination with a casing having two valve-controlled inlets andtwo valve-controlled outlets, of a valve device in said casing providedwith two valves which move simultaneously and are provided each with twoseats and adapted to close either one of said outlets or both of saidoutlets together and to move differentiallyv with respect to saidoutlets, substantially as described 4. A Valve device comprising acasing with four valve se'ats in pairs each of which comprises two seatsfacing each other, a valve between each of said two pairs of seats andmeans for moving the two valves simultaneously so as to close the pairsof seats in either direction simultaneously or to open themdifferentially, substantially as described.

5. In a valve the combination with a casing having two valve-controlledinlets, and two outlets having each a valve chamber therein providedwith two seats, of a pair of valves, one in each of the outlet chamberseach provided with two conical surfaces one of which is of greaterinclination than the other, whereby the valve may move further into itsseat in one direction than in the other, and means for moving saidoutlet valves simultaneously in either direction to co-operaterespectively with either one of the seats in said chambers.

In testimony whereof I have hereunto set my hand in the presence of thesubscribed witnesses.
